围护结构对辐射供暖影响的初步分析

以辐射供暖系统下的围护结构为研究对象,通过分析辐射面材料的蓄热性能与辐射采暖空调系统启停时间的关系,以及外墙个数和类型的不同对室内热环境以及能耗的影响,得出辐射面材料的蓄热系数越大,热稳定性越好,温度变化的滞后时间也越长.外围护结构数量不同会引起地板辐射采暖室内热环境的较大变化,为了满足室内舒适度的要求,随着外墙个数的增加,应提高地板表面温度.

Preliminary analysis of enclosures on the impact of radiant cooling and heating

Aimming at the building envelopes in the radiant cooling and heating system,this paper analyzes the relationship between the thermal storage performance of radiant surface's materials and start-up or shut down time of heating and air-conditioning system.The impact of the external walls with different number and different types on indoor thermal environment is studied.It comes to the conclusion that the thermal storage coefficient of radiant surface's materials is greater,which will lead to better thermal st...
